Application filed April 25,

T all whom it may concern:

Be it known that l, HERMAN ScI-inninn, a citizen of the United States, and resident of Sheboygan, in the county of Sheboygan and State of lVisconsin, have invented cer tain new and useful Improvements in Ventilator Hoods for Windows; and Ido hereby declare that the'following is a full, clear, and exact description thereof.

My invention refers to window ventilators and it has for its primary object to provide a simple, economical and effective metallic ventilator hood adapted to be fitted to the upper portion of a window casing, whereby the window may be lowered to permit ventilation of the room, the construction and arrangement of the hood being such that while it permits free circulation of air, it will at the same time prevent rain or gusts of wind from entering through the open portion of said window. In other words, the ventilator hood will produce the desired re sults of ventilating without the liability of creating of drafts, or admitting rain or snow.

Another object of my invention is to provide a ventilator which can be cheaply manufactured primarily from sheet material, whereby reduction in cost of the manufacture is obtained.

lVith the above and other minor objects in view, the invention consists in certain peculiarities of construction and combina tion of parts, as are hereinafter set forth with reference to the accompanying drawings and subsequently claimed.

In the drawings:

Figure 1 represents a sectional elevation of the window having attached thereto a ventilating cap or hood embodyingthe features of my invention,

Figure 2 is a face view of the same, upon an enlarged scale, looking from the inside of the structure, with parts broken away and in section to more clearly illustrate the structural features.

Figure 3 is a plan view, partly in section, as indicated by line 33 of Figure 2, and

Figure 4 is a detail corner section illustrating another method of attaching the hood to the outer edge of a window frame, in which instance, end panels of the hood may be flanged outwardly.

Referring by characters to the drawing, A. represents one type of window casing, 13 the slidable sash mounted therein, and C a screen 18-22. Serial No. 556,262.

which is fitted outside of the sash in the usual manner. Fitted to the upper end of the window frame is a metallic ventilator hood, the body of which hood is preferably formed from ametallic blank having a front panel 1, the ends of which are bent inwardly to form end panels 2, which panels are suitably apertured near their inner edges for the reception of retaining screws 3, which are secured to faces of the window frame A. The hood body thus forms a rectangular box-like structure having an open bottom at for ventilating purposes and the partly closed roof-top 5, which top connects the upper edges of the end panels 2.

i The outer portion of the roof-top is folded downwardly to form a deflecting flange 6 between which fiange and the adjacent edge of the front panel a bent opening is formed, whereby liability of a dead air space is eliminated at this location of the hood. The opening formed between the downturned portion 6 and front panel 1 permits the heated air to rise and pass outwardly from the device. This is particularly desirable where there is no draft of air acting in a pronounced manner. However, when the desired draft occurs the air will takethe general path indicated by the arrows in Figure 1. The inner edge of the roof-top is slightly, flared in an. upward direction and approximately abuts the screen frame C so to form a comparatively tight joint at this point.

In order to prevent rain or snow from beating into the hood and its dead air vent, the shield plate 7 is secured to the upper edge of the front and end panels and presents an oblique or inwardly inclined surface to the weather, and the ends of said plate are folded downwardly to form closure webs 7 between the shield and end panels 2 of said hood. Hence the upper portion of the hood is rendered water-tight in all directions; By providing the shield plate 7 any snow or rain that driven against the apparatus is deflected downwardly exteriorly of the front panel in an obvious manner. However, it is to be noted that under unusually severe conditions where the wind is blowing directh against the window it is possible that snow or rain to a small extent may be driven over the upper edge of the shield 7. When this happens it merely falls upon the portion and is deflected downwardly and outwardly by venting; its entrance into the re In order to eliminate any possibility of water from dripping into the hood from the dead air vent, or slot, that is formed by the flange 6, I may, in some cases, attach at the base of said flange a rib member 8 which projects upwardly and thereby serves-as a trap to prevent moisture from dripping down into the body of the hood from above. Referring especially to Figure 4 ,of the drawings, if in some cases it is desirable to attach the ventilator hood at the outer edge of the window frame, I may form end panels with off-set flanges 2, which flanges re apertured for the reception of" retain screws 3, as indicated in Figure 4c.

'lVhile I have shown and described one simple exemplitication of my invention in all of its details, it is understood that I may vary'the structural features within the scope of the claims, as they may be hereinafter 1nterpreted by those skilled in the art. 7

I claim 1, A ventilator hood for attachment to the upper portion of a window casing, the

same comprising a front panel having inturned end panels attachable to the win- :2. A ventilator hood for attachment to a window casing, the same comprising a metallic body having a front panel and end panels, the end panels being provided with means for attachment tothe upperportion of the window casing, a roof-top connecting the end panels, the outer end of the rooftop being folded downwardly to form a longitudinal vent at the upper edge of the front panel, and a flaring shield member eXtending upwardly from the frontand end panels to form a deflector, whereby rain or snow may be shedded from the upper portion of the hood, the lower portion of the front and end panels forming a mouth through w iich air currents may travel from the upper portion of the window when the sash is moved a predetermined distance for ventilating purposes.

3 A ventilator hood for attachment to the upper portion of a window casing comprising a structure including a front panel, end panels, and a roof top section integrally connecting the end panels, said roof top section having a downturned deflecting flange adjacent its outer portion and spaced from the front panel to provide a vent slot and an upwardly inclined weather shield at tached to the top edge of the front panel and end panels and extending: upwardly therefrom over said roof top section whereby water is deflected from the upper top .portion of the hood.

In testimony that I claim the foregoing .I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of Wisconsin.
